Problems solved by technology

However, in this solution, the size of the grinding head cannot be adjusted and does not match the inner diameter of the blood vessel. The polished vascular garbage will flow to other parts of the blood vessel and accumulate, which may form a secondary embolism. There is a problem of incomplete cleaning of vascular garbage. question

Embodiment 1

[0045] Such as figure 1 As shown in the blood vessel dredging device described in this embodiment, the guide wire 3 extends to the other end of the elastic capsule head 1 and is connected to the other end of the elastic capsule head 1 . By pulling the other end of the guide wire 3, the other end of the elastic capsule head 1 moves toward the sleeve 2, the distance between the two ends of the elastic capsule head 1 decreases, and the elastic capsule head 1 Deformation under force can increase the length of the elastic capsule head 1 in the radial direction; when the guide wire 3 is loosened, the force on the elastic capsule head 1 gradually disappears, and the two ends of the elastic capsule head 1 The distance between them increases and the length in the radial direction decreases, which can be used to adjust the size of the elastic capsule head 1 in the radial direction to match the inner diameter of the blood vessel.

[0046] Preferably, the shape of the elastic capsule hea...

Embodiment 2

[0051] Such as image 3 As shown, the blood vessel dredging device described in this embodiment is different from the first embodiment in that the other end of the guide wire 3 passing through the elastic capsule head 1 is provided with a fixing part 31 .

[0052] The maximum dimension in the radial direction of the fixing portion 31 is larger than the size of the hole formed by passing the guide wire 3 through the other end of the elastic capsule head 1 . When the guide wire 3 is pulled, the fixing part 31 on the guide wire 3 moves toward the other end of the elastic capsule head 1, and the fixing part 31 and the sleeve 2 squeeze the elastic capsule head together. The two ends of the bladder head 1 reduce the distance between the two ends of the elastic bladder head 1, and the elastic bladder head 1 is deformed under force, so that the radial length of the elastic bladder head 1 increases; When the guide wire 3 is opened, the force of the elastic capsule head 1 gradually dis...

Embodiment 3

[0055] Such as Figure 4 As shown, the blood vessel dredging device described in this embodiment also includes a transmission mechanism 4 that drives the elastic capsule head 1 to rotate around the central axis of the sleeve tube 2, and the other end of the sleeve tube 2 is connected to the transmission mechanism 4. One end of mechanism 4 is connected.

[0056] Further, the transmission mechanism 4 includes a fixed sleeve 41, a bearing 42 and a transmission shaft 43, the transmission shaft 43 passes through the bearing of the shaft 42, and one end of the fixed sleeve 41 is connected to one end of the transmission shaft 43, The other end of the fixing sleeve 41 is connected with the sleeve 2 .

[0057] The fixed sleeve 41 can be provided with a variable diameter through hole inside, one end of the fixed sleeve 41 is connected with the sleeve 2, the other end of the fixed sleeve 41 is connected with the transmission shaft 43, and the transmission shaft 43 is provided with a st...

Abstract

The invention discloses a blood vessel dredging device and a blood vessel dredging cleaner. The blood vessel dredging device comprises a sleeve, a guide wire and an elastic bag head, one end of the elastic bag head is connected with one end of the sleeve, the guide wire partially penetrates through the sleeve and the end, connected with the sleeve, of the elastic bag head in the axial direction ofthe sleeve to extend towards the other end of the elastic bag head, a fixing part matched with the other end of the elastic bag head is arranged on the guide wire in the direction away from the sleeve, and the fixing part is at least used for decreasing the distance between the two ends of the elastic bag head when the guide wire is pulled. By arranging a guide pipe and a suction device, The blood vessel dredging cleaner can suck out blood vessel garbage cleaned by the blood vessel dredging device. By pulling the guide wire, the maximum radial size of the elastic bag head is changed to be matched with the inner diameter of a blood vessel, and thus the situation that cleaned blood vessel garbage flows to other positions along with blood to form secondary embolism can be effectively avoided.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a blood vessel dredging device and a blood vessel dredging cleaner. Background technique [0002] Blood vessels are an important part of the cardiovascular system. After blood leaves the heart from the arteries, it is distributed to various organs and parts of the body through blood vessels to provide nutrition for them, and then returns to the heart through veins. In addition, blood vessels are distributed throughout the body. To provide oxygen and other nutrients to the cells of major organs, muscles and nerves. When the blood vessel is damaged, the blood flow is sluggish, and the blood is hypercoagulable, thrombus will form. The thrombus will narrow the blood vessel or cause embolism. die. [0003] There are many ways to treat vascular embolism. The Chinese patent application number 201810073578.8 discloses a cleaner for blood vessel dredging, in which the grindi...
